Do antenna tuners work?
Do antenna tuners work?
Despite its name, an “antenna” tuner does not actually tune the antenna. If the loss of power is low in the line carrying the transmitter’s signal to the antenna, a tuner at the transmitter end can produce a worthwhile degree of matching and tuning for the antenna and feedline network as a whole.
Does an antenna tuner improve reception?
Member. Your right, an antenna tuner WILL help you on receive. The radio is going to work better receiving off a 50 ohm in feed. In fact, most guys with antenna tuners will use the noise floor or a received signal to begin tuning their antenna tuner.
How do I manually tune my antenna?
Steps
- Make sure that the antenna (aerial) cable is properly connected to the TV.
- Press the HOME button, then select [Settings].
- Select [Digital Set-up] → [Digital Manual Tuning].
- Select [Scan Type], then select [Channel] or [Frequency].
- Set the other items accordingly.
- Select [Scan Up] or [Scan Down].
Do I need an antenna tuner with an amplifier?
Yes, you’ll need an external tuner, unless your antenna is already matched sufficiently well to 50 ohms. The objective of the tuner is to transform the impedance seen by some signal source, like your radio, or the amplifier.
How do I choose an antenna tuner?
Select the one that gives the best range, etc. Different antenna tuners will be able to provide a match over different ranges. Examples include the MFJ928 and MFJ939 which both provide a match over the range 6 to 1600Ω. Other antenna tuners will be able to match over different ranges so a judgement needs to be made.
Does SWR meter go before or after antenna tuner?
A wattmeter will only be accurate when terminated with a 50 ohm load, so placing the meter between the radio and tuner will give the best power reading when the tuner is tuned.
Why is my TV not picking up channels?
First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
Do you need an antenna tuner for VHF?
On the VHF/UHF bands, antenna bandwidth is not as much of an issue. A 2 meter antenna with 7% SWR bandwidth (nominal bandwidth for a Yagi), will easily cover the whole 2 meter band with a reasonable SWR. So if the antenna is tuned properly, no tuner is needed.

How much power is lost in an antenna tuner?
A 40m dipole exhibits a moderate impedance on 15m because it’s close to being 3/4 wavelength long; that keeps the losses in the coax manageable. But if you operated a 40m dipole on 20m you might expect about 10dB loss in 100ft of RG213 feedline and – depending on coax length – over 30% power lost in the tuner.
